Signs & Symptoms of Eye Migraines
An eye migraine may also be called a ocular migraine or a ophthalmic migraine. It is caused by a constriction of the blood vessels that carry blood to the eye, and it can last anywhere from five minutes to 30 minutes. An eye migraine that affects one eye is called a retinal migraine, while an eye migraine that affects both eyes is called a migraine with auras. This condition can be confused with a stroke or with other serious disorders, and correctly identifying the signs and symptoms will lead to a faster diagnosis.-
Temporary Vision Loss
-
According to WebMd.com, about 50 percent of people who have an eye migraine will suffer complete vision loss in one eye. Though this is frightening, this symptom is temporary, and a permanent loss of vision is very rare. In the case of a migraine with auras, this will affect both eyes.
Scotomas
-
Scotomas are blank or black spots in your vision that may occur during an eye migraine. They are usually steady and occupy a place in the center of your vision, rapidly growing larger.
Scintillations
-
Scintillations are bright flashing lights that may cross your vision if you are having an eye migraine. They are often paired with scotomas. These lights may seem to be flickering or they might seem to be moving in a zig-zagging line.
Distorted Vision
-
An eye migraine may result in a distortion of vision, and your eyes may be giving you information that you know is not true. An object may appear to be larger or smaller than it is, or you might not be able to judge distances. Straight lines might seem to waver or to be curved. Your vision may also seem to be blurred.
Headaches
-
According to WebMD.com, 41 percent experience a headache during vision loss in an ocular migraine, while 25 percent experience a headache before or after the vision loss occurring.
